The probability that exactly six out of ten carry a smartphone when travelling is; <u><em>P(6) = 0.146</em></u>
The missing part of the question is;
The probability distribution of x is the binomial distribution with n = 10 and p = 0.75.
Calculate P(6)
- This is a binomial <em>probability distribution</em> problem that has a general formula as; P(x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾
Where;
p is probability of success
q is probability of failure
n is number of experiments
In this question;
n = 10
p = 75% = 0.75
q = 1 - p
q = 1 - 0.75
q = 0.25
Since six passengers are randomly selected, then applying the formula earlier quoted, we have;
P(6) = ¹⁰C₆ × 0.75⁶ × 0.25⁽¹⁰ ⁻ ⁶⁾
P(6) = 0.146

Answer:
Step-by-step explanation:
From your knowledge of multiplication tables, you know ...
48 = 6·8 = 3·2·2·2·2 = 3·2^4 . . . . a = 4
56 = 7·8 = 7·2·2·2 = 7·2^3 . . . . . . b = 3
Answer:
−13x+18
Step-by-step explanation:
=−4x+(−9)(x)+(−9)(−2)
=−4x+−9x+18
Combine Like Terms:
=−4x+−9x+18
=(−4x+−9x)+(18)
=−13x+18
